A common misconception is that you need a web server like IIS, Apache, or Nginx to get started with PHP7 development. In fact, PHP7 has its own built in web server that you can invoke at the command prompt. Many modern PHP frameworks support this, such as Phalcon PHP.

The WordPress REST API has been available since 4.7. It’s robust, consistent, and nifty to work with. Why? Backend and mobile developers can use other frameworks while still keeping WordPress around for their customers. Frontend developers can build sites using JavaScript without having to touch PHP. Up is down, left is right, dogs and cats living together… Let’s get started!

Comment out the class_alias() functions in phpunit6-compat.php because these break PhpStorm code completion. (These files aren’t actually used by the testing framework, we only downloaded them so they could be included in the Project Configuration’s Include Path.)

This time, I participated in a 2 day crash course given by agile coach Pawel Mysliwiec of Pyxis. The course was in French. It was much better than studying alone. It was fun to meet like minded Scrum practitioners.

I took the test April 9, 2017 and passed. My Score was 74 points (or 92.5%)

Many people dislike WordPress code. It’s no secret that for contemporary PHP developers WordPress feels antiquated. The founder of WordPress was even once-upon-a-time vocal about not keeping up to date with the PHP eco-system because reasons.

Times changed. So did PHP. So did WordPress.

To give credit where credit is due, the reasoning behind WordPress’ conservative change management is sound. They don’t want to mess with their insanely huge user base.

The good news is that when you develop for WordPress you don’t ever touch WordPress code. Instead you write a Plugin. [1] I put forward that in 2017 nothing is stopping you from writing a good, clean Plugin other than yourself.

First attempt, creating deadlocks

In the following proof of concept, where we have 50 of the same product in stock, and we run seige to represent concurrent customers buying the same product at the same time, we expect 50 “Success!” messages in our log files.

When we use any of REPEATABLE READ, READ UNCOMMITTED, or READ COMMITTED we oversell. (boo!)

When we use SERIALIZABLE we do not oversell (yay!) but some users get deadlock errors while others do not. (SQLSTATE[40001]: Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction)

Ever wanted to make a bugfix to a Composer package? You can!

Get a local git clone of the dependency by requiring it with the –prefer-source option.

composer require kizu514/package --prefer-source

But wait that’s not all! If you have your own GitHub namespace you can set things up so that your own code is always installed from source. For example, In the following composer.json snippet all the packages from kizu514 are installed from source, and everything else is dist.

A manifest turns a responsive website into an installable app. It lets users add it on their mobile phone’s home screen. When they launch the site it gets a splash screen and runs in full screen mode, basically behaving like a native app.

Caveat: For this to work HTTPS is required. Use certbot if you don’t already.

I used Manifest Generator to get started and it was easy. According to the ConFoo talk Bing indexes sites with manifest.json files and prioritizes them as smartphone compatible. A simple SEO win?
